WebPulsus bisferiens, also known as biphasic pulse, is an aortic waveform with two peaks per cardiac cycle, a small one followed by a strong and broad one. [1] It is a sign of problems with the aorta, including aortic stenosis and aortic regurgitation, as well as hypertrophic cardiomyopathy causing subaortic stenosis. [1] WebOct 27, 2024 · A pulse is a rhythmic wave produced by ventricular contraction during systole. A double pulse noticed during systole in the peripheral pulse is called pulsus bisferiens. This is derived from the Latin word, which means strike twice (bis=twice, ferio=strike). It is also called a biphasic wave. Way back in 1952, it was described by …

WebJan 21, 2024 · 3 Hz and spike-wave: These are typical for absence seizures but can also occur in other types of generalized seizures. The waking background EEG activity is normal. The spike-and-wave is a bi-synchronous, symmetric discharge of sudden onset and resolution with a frequency of 3.5 Hz to 4 Hz at the onset, slowing to 2.5 Hz to 3 Hz at … WebFeb 26, 2024 · Correlating the waveforms with the ABI ratios helps decipher the cause of the biphasic waveforms. For example, if the ABI is 1.0 and the waveform is biphasic, there could be mild calcification in the vessels but no significant atherosclerosis. Biphasic waveforms obtained with an ABI of 0.7 indicate mild to moderate PAD. little boy getty images
